Answer:
68 students
Step-by-step explanation:
Number of men who major in business in the university= 0.43*8253=3548.79
Rounding off we have 3549 students
Number of women who major in business in the university= 0.27*10327=2788.29
Approximately 2789 students
Total students who major in Business= 3549+2789=6338 students
Total students in school= 8253+10327=18580
Probability of getting business major= 6338/18580
Out of 200 students, we expect
Approximately 68 students will be majoring in business
The vertex is the point where the graph is horizontal, which you can find by setting the first derivative to zero.
derivative: -4x + 8 = 0 => x=2
fill it in in the equation:
y=-2*2² + 8*2 - 5 = 3
So the answer is the point (2,3)
Answer:
11. 16
12. -19
13. -9
14. -5
15. -13
Step-by-step explanation:
For the first part:Every shirt she grabs, will cost her dollars, so if she grabs 3 shirts, then the cost of the shirts is:
With the same rationale, if she grabs 2 pairs of jeans, the cost of the jeans is:
So, her total is:
If you subtract 3 from the total, then the expression is:
For the second part:If she's paying 3 less for each shirt, then the cost of 3 shirts will become:
In the same fashion, for the two jeans:
So the expression for the total cost is:
For number three:The amounts are different because the cost of the total purchase is different than the cost of each element that makes up the total purchase.
For number four:If you're the owner, you want to give the smallest amount of discount (the one in part 1/a).
So you could clarify by saying there's 3 dollars of the TOTAL purchase's cost.
